18 The selected explanatory variables:Must be linearly related to the dependent variable,Must be highly correlated with the dependent variable,Must not be highly correlated between themselves,Must lend themselves to relatively easy projection.

39 TRIP-RATE Analysis[Papacostas & Prevedouros, 1993]Trip-rate analysis refers to several models that are based on the determination of the average trip production or trip attraction rates associated with the important trip generators within the region.

43 Cross-Classification Models[Papacostas & Prevedouros, 1993]Cross-classification (or category analysis) models may be thought of as extensions of the simple trip-rate models.Although they can be calibrated as area- or zone-based models, in trip-generation studies they are almost exclusively used as disaggregate models.
